BACKGROUND OF THE INVENTION

[0002] The new plant of the present invention comprises a new anddistinct cultivar of chrysanthemum plant that is a natural occuringsport of a parent chrysanthemum named PEARL REAGAN MUNDO. A comparisonwith Parent chrysanthemum PEARL REAGAN MUNDO is also made in thisapplication. The new cultivar was discovered as a whole plant mutationin September 1996 by Rob Noodelijk in a controlled environment(greenhouse) in Rijsenhout Holland. The first act of asexualreproduction of WHITE REAGAN MUNDO was accomplished when vegetativecuttings were taken from the initial selection in November 1996 inRijsenhout Holland.

SUMMARY OF THE INVENTION

[0003] The present invention is a new and distinct variety ofchrysanthemum bearing medium sized blooms with white ray-florets andyellow-green disc florets.

BRIEF DESCRIPTION OF THE DRAWINGS

[0004] The present invention of a new and distinct variety ofchrysanthemum is shown in the accompanying drawings, the color being asnearly true as possible with color photographs of this type.

[0005]FIG. 1 shows a stem of the cultivar in full bloom.

DESCRIPTION OF THE INVENTION

[0006] This new variety of chrysanthemum is of the botanicalclassification Dendranthema grandiflora. The observations andmeasurements were gathered from plants grown in a greenhouse inRijsenhout Holland in a photo-periodic controlled crop. Thephoto-periodic response time in this crop was 50 days. This new varietyproduces medium sized blooms with white ray-florets and yellow-greendisc-florets blooming on the plant for 28 days. This new variety ofchrysanthemum has been found to retain its distinctive characteristicsthroughout successive propagations however the phenotype may varysignificantly with variations in environment such as light intensity andtemperature. To show the phenotype as described WHITE REAGAN MUNDO maybe planted without assimilation lightning between week 50 and 40 undergreenhouse conditions in Holland. With assimilation lightning (minimumlevel 2500 lux) it may be planted year round under greenhouse conditionsin Holland.

[0007] The variety WHITE REAGAN MUNDO is a natural mutant of PEARLREAGAN MUNDO. The variety PEARL REAGAN MUNDO is a natural mutant ofREAGAN. When WHITE REAGAN MUNDO, PEARL REAGAN MUNDO and REAGAN are beingcompared the following differences and similarities are noticed: (A) Thedifference of WHITE REAGAN MUNDO and PEARL REAGAN MUNDO is the flowercolor for which characteristic WHITE REAGAN MUNDO has been selected outof PEARL REAGAN MUNDO. All other characteristics of WHITE REAGAN MUNDOand PEARL REAGAN MUNDO are the same. (B) The differences of PEARL REAGANMUNDO and REAGAN are (1) flower form (2) flower size (3) flower color(4) spray formation and flower count and (5) tolerance for a lower nighttemperature for which characteristics PEARL REAGAN MUNDO has beenselected out of REAGAN. All other characteristics of PEARL REAGAN MUNDOand REAGAN are similar. (A) Flower color: WHITE REAGAN MUNDO has whiteray-florets instead of pale pink ray-florets. (B) (1) Flower form: Theray-florets of PEARL REAGAN MUNDO are less broad and more pointed andthey are more upright. The flower-disc is smaller, greener and moreregular. (2) Flower size: The flower is a little smaller. (3) Flowercolor: The flower color is paler (4) The spray formation: The sprayformation is more flat, less pyramidal, mostly a little wider and theflower count is higher. (5) Temperature tolerance: PEARL REAGAN MUNDOand all its color mutants can be grown at a lower night temperature. Therequired minimum temperature for REAGAN (under all circumstances) is 17°C. Under high light conditions PEARL REAGAN MUNDO can be grown at 14° C.This has been tested and confirmed in poor heated crops under high lightconditions flowering in February 1997 and 1998 in Italy and Spain.

[0008] The following is a description of the plant and characteristicsthat distinguish WHITE REAGAN MUNDO as a new and distinct variety.

[0009] The color designations are taken from the plant itself.Accordingly, any discrepancies between the color designations and thecolors depicted in the photographs are due to photographic tolerances.
